Wafer-based production of precision optics

In the field of optical components, LIMO is currently one of the world’s major suppliers of glass cylindrical lenses thanks to its highly productive wafer-based manufacturing technology. LIMO specializes in precision optics for all diode laser types (single emitters, bars, and stacks) and all power classes.

The wafer-based production technology -  a wafer lever simultaneous structuring process with complementary polishing -  with wafer sizes of up to 300 x 300 mm² makes it possible to produce tens of thousands of lenses from high-grade glass and crystal in a single process step, with a consistently high level of quality. Combined with a significantly expanded production capacity, LIMO’s highly productive and cost-efficient operations mean that the company can continue to meet the growing global demand for optics in innovative photonics- and laser-based applications and technologies well into the future.
